Answer:

Triassic Period (252 to 201 million years ago)

All continents during the Triassic Period were part of a single land mass called Pangaea. This meant that differences between animals or plants found in different areas were minor.

The climate was relatively hot and dry, and much of the land was covered with large deserts. Unlike today, there were no polar ice caps.

It was in this environment that the reptiles known as dinosaurs first evolved. Reptiles tend to flourish in hot climates because their skin is less porous than, for example, mammal skin, so it loses less water in the heat. Reptile kidneys are also better at conserving water.

How is cytokinesis different in animals and plants? Animal cells get pinched into two daughter cells by the cell membrane; the p

jasenka [17]

<h2>Let's review what cytokinesis is first.</h2>

Cytokensis is the physical process of cell division. It divides the cytoplasm of a parental cell into two different daughter cells.

In plants, a cell wall forms. Cytokensis occurs in mitosis and meiosis. The objective for cytokensis is to divide the parent cell into two daughter cells. So cytokensis in plants is when a cell wall forms in between the daughter cells. Plant cells have walls, so they CANNOT divide using a cleavage furrow. A cell plate forms across the cell during telophase.

In animal cells, cleavage furrow forms. This pinches the cell in half and forms two different cells.

A cleavage furrow is an indentation that appears in the cells surface when the cell is preparing to divide.

So, let's review our options:

A: Animal cells get pinched into two daughter cells by the cell membrane; the plant cell has to form a cell plate before it can create daughter cells.

This would be the correct answer. The only main difference between animal cell cytokensis vs plant cell cytokensis is the cell wall that animal cells lack. Animal cells get pinched into two daughter cells, by the cleavage furrow in the cell membrane, while the plant cell has to form a cell plate before it can create daughter cells.

B: Animal cells give daughter cells a full set of chromosomes at the time of division; plant cells give daughter cells a half set of chromosomes. .

This can be disproven. In meosis, a cell divides into four cells that have half the number of chromosomes. In mitosis, all chromosomes are kept. Both Plant & Animal cells both reproduce using both both meosis and mitosis, so this option is irrelevant.

C: Animal cells require an extra grow phase before cytokensis; plant cells move straight to cytokensis.

Both animal cells and plant cells have the same amount of "grow phases" before cytokensis. This option is irrelevant.

D: Animal cells begin cytokensis during anaphase, plant cells begin around the same time as telophase.

They both begin during the same time. This option is also irrelevant.

Answer:

Within the bone marrow, all blood cells originate from a single type of unspecialized cell called a stem cell. When a stem cell divides, it first becomes an immature red blood cell, white blood cell, or platelet-producing cell.
